Question 1 of 20
What is the primary function of a logic gate?
Logic gates are designed to perform logical operations based on input signals.
Question 2 of 20
Which mathematical system is used in the operation of logic gates?
Logic gates operate based on the principles of Boolean algebra.
Question 3 of 20
Which of the following is NOT a basic logic gate?
NAND is a universal gate, not a basic gate.
Question 4 of 20
Which gate is known as a universal gate?
NAND and NOR gates are considered universal because any logic function can be implemented using only these gates.
Question 5 of 20
What are the possible output values of a logic gate?
Logic gates use binary values, represented as 0 and 1.
Question 6 of 20
What is the function of an AND gate?
An AND gate outputs HIGH (1) only when all its inputs are HIGH (1).
Question 7 of 20
What is the function of an OR gate?
An OR gate outputs HIGH (1) if at least one of its inputs is HIGH (1).
Question 8 of 20
What is the function of a NOT gate?
A NOT gate inverts its input; if the input is HIGH, the output is LOW, and vice versa.
Question 9 of 20
Which component is most commonly used to build logic gates?
Transistors act as electronic switches and are the building blocks of logic gates.
Question 10 of 20
What does a truth table describe?
A truth table shows the output of a logic gate for every possible combination of inputs.
Question 11 of 20
What is the output of a 2-input AND gate if the inputs are 1 and 0?
In an AND gate, the output is only 1 if both inputs are 1; otherwise, the output is 0.
Question 12 of 20
What is the output of a 2-input OR gate if the inputs are 1 and 0?
In an OR gate, the output is 1 if at least one input is 1.
Question 13 of 20
What is the output of a NOT gate if the input is 1?
A NOT gate inverts the input.
Question 14 of 20
Which gate's output is LOW only if all inputs are HIGH?
NAND gate outputs LOW (0) only when all inputs are HIGH (1).
Question 15 of 20
Which gate's output is LOW if any input is HIGH?
A NOR gate outputs LOW if any input is HIGH.
Question 16 of 20
Logic gates are primarily built on which type of circuits?
Logic gates are fundamental to digital circuits.
Question 17 of 20
Which of the following is an advantage of logic gates?
Logic gates are known for their high reliability.
Question 18 of 20
What is a major limitation of logic gates?
Logic gates operate with only binary (0 and 1) voltage levels.
Question 19 of 20
Where are logic gates commonly used?
Logic gates are foundational to computer design and function.
Question 20 of 20
What is the purpose of the ground terminal in a logic gate circuit?
The ground terminal provides a 0V reference point.
